Actually the real problem comes from french communities, Rangorn comes from here, so do I, a lot of people...
I won't defend him but you have to know french servers are shitty af because :
1) We don't share anymore, the reason is "blah blah I want exclusivity, I want to be the first blah blah", "I don't want to be stealed by John Doe/Jane Doe", some servers (Hi Stormheim if you see me) are developping their own server and what will happen if they fail ? Nothing, they will keep their sources instead of giving a better workbase for Legion. That's why I applause some servers like Sunwell. They close, they release their sources, Nostalrius same, they releasead everything as a sandbox (it's not fantastic but it's still a great gift)
2) People are lazy, actually people are crying for a good repack instead of compiling a core, and after they yell on us because we refuse to help them for a simple reason : they choose the easiest way, they have to deal with.
At least, this selfish mentality is implanted in every french brain since people said "I won't share anymore, you don't deserve my work", I'm in WoW Emulation for... 8 years now, when I came in, people were nice, helping, and they shared everything (when I say everything, I thought about a full sex shop in Ironforge, a gossip whore system etc...), but after 4 years and 3 new "better" communities I saw nobody was able to help because of lazy teenagers without any skills.
I don't share any file or program except ones I don't really care (like humans HD models, soon Gnomes etc...), it's a huge load of work but with Meta we agree about one thing : It's not the best asset of our project, so, well we can give it to you. Same thing for my tutorials, I share it not because nobody know how to do thing X or Y but one day one guy can need it and I don't want this guy loses his time searching in a dusty dead forum, I post my tutorials because I'm proud to show you I can do something and modding and it remains me nobody knows everything. Even the smallest tutorial in the world is useful
I don't care if you think WoD is better than TLK, I won't use WoD because this client has a lot of useless things for my project and I'll lose so much time if I have to disable every useless little thing.
